Pressure of the Fuel Supply To the Carburetor
The gas pressure regulator maintains a pressure differential between the air and the fuel that is supplied to the carburetor. After setting, the gas pressure regulator will maintain the pressure differential in response to changes in the air pressure.
Set the pressure of the fuel supply using the chart found in Special Instructions, REHS6590.
